Juanes

The only instrument you notice walking into Juanes' sun-dappled home on Key Biscayne is an upright piano, covered with lesson books for his daughter Paloma, 7, who on this weekday morning is sprawled on a sofa, along with siblings Luna, 9, and Dante, 3, in pajama-clad, spring-break bliss.

The 19 Grammy Awards, racks of guitars and other trappings of the 40-year-old Colombian rock star's career are in his recording studio upstairs.
